Does anyone know of an app for Mac OSX or OS9 that can equalize at least the volume of a bacth of mp3.
I've got a buch of mp3's, all diff. volumes and I want to burn a CD, but I'd like for it all to be even when I burn it. Know what I mean? Any help would be appreciated. |

I'd love an OS9 answer to this questionas well... I've got about 300 mp3's I'd like to use for a stream on the net and the levels are all different (though relatively close on most - but a few are way off)

There are differences in volume, both real and apparent, from song to song and album to album. Some is due to mastering technique. You won't be able to do anything about that. Two different songs peaking at 0 dB can sound, volume-wise, very much different.
The reason you don't notice these differences on the radio is because the stations broadcast through processing like compression and limiting. A lot of mp3s you get from 'sharing' with your 'peers' are poorly made and the volume differences are due to that. The only way I know how to change the level of an mp3 is to convert it to an AIFF, change it with one of many apps, then convert it back to mp3. It will probably sound like crap, too. |

i agree with BagHun... there really is no quick and easy fix for what you guys seek that I know of... basically it would mean you would have to remaster each track one by one and depending on how important this is to you... it probably won't be worth the time and effort.
the only thing that I know of that would work somewhat is using an app like SoundJam for audio playback... in SoundJam, you can set gain for each mp3 in your library and it will remember the gain setting plus you can make give each mp3 its own EQ settings as well and its remembered whenever you open that song back into SoundJam. -------------------- ----------------------------------------

i would suggest you try :- A. normalizing all files first (i'm sure you did that), B. a program like t-racks or a plug like master x from tc or c4 from waves to soft limit the files that appear quieter, this allows a file to become much louder without changing the sound (digital limiter) and C. use a program like jam from roxio/adaptec to finely balance the levels between each track by ear before burning. lastly, not a lot of people realise that it can be very important to use dc offset removal before you do any of these other processes, removing the dc offset will make sure that any level adjustment of different files will ensure that they are adjusted by the exact same amount. in the world of dc offset, all files are not equal!!! good luck, anything else i can do to help, just ask.
